check the internal resistance of your fuel injectors. I believe they are supposed to be 8 ohms.

o2 sensor?? Could be on its way out

croketa1

well thats the thing, i dont have any check engine light on

Mine would misfire due to bad coils and I had no CEL either. It just could be on the edge of the tolerance and the computer is not picking it up until it gets worse.

oh i see , weel check this out i put in it all new spark plugs, and on the driver side the front 2 ones were kinda dark, when all the others were whitish, so im not sure now, but then again fuel pressure goes down after 3k rpm when punching it

jtb727

White plugs are nothing but bad news, does your fuel pressure fall after 3k? is the duty cycle of your injectors changing at 3k? you need to measure your fuel pressure, and make sure your getting full pressure to the injectors consistantly in the RPMS. Than see if your duty cycle is changing, if you do have correct fuel pressures..

White plug= lean condition= mucho damage my friend.
